Results varied experiences statistical analysis between the two samples of the three metrics , and results varied between grades as well as the pieces of the two extremes in giving clear results unreliable. 2 . Results between the two samples proved that the size of the sample ( 400 ) individual best number in the improvement in the accuracy of Statistics to give discriminatory sincerity and genuineness good internal consistency for the construction of scales , from the size of the sample is equal to ( the number of paragraphs of any scale * ( 5 ) members each paragraph ) . 3 . Unresolved results of any degree cut from grades three segments (25 % .27 % .33 % ) , according to the literature of measurement is the best between the two extremes for my sample construction in giving good results to improve the accuracy of statistics paragraphs , and finally recommended that the researcher has proposed recommendations and proposals of several serving studies and theoretical literature measurable psychological .
